2002–2006 Acura RSX Base Cold Air Intake
A less restrictive intake path can make an RSX Base feel more responsive when the throttle opens and add a deeper induction note during acceleration. This Flashark cold air intake kit is designed for the 2002–2006 Acura RSX Base and uses aluminum intake piping, a heat-shield-style layout, and a washable, reusable cone filter.
For owners searching for an air intake RSX, intake RSX, or RSX air intake, this kit is listed specifically for the Base model. It is not listed for the Acura RSX Type-S, so Base and Type-S intake systems should not be treated as interchangeable.

Key Features for the RSX Base
- Aluminum intake piping replaces the restrictive factory intake path with a smoother route to the engine.
- Heat-shield-style layout helps separate the filter area from surrounding engine-bay heat.
- Washable and reusable cone filter supports routine service rather than disposable-filter replacement.
- Designed to make induction sound more noticeable under acceleration while retaining a quieter character during light-throttle cruising.
- Can support a sharper throttle feel through the low- and mid-RPM range when the intake system is installed correctly and free of leaks.
What Is Included
- 1 x performance cold air intake kit
- Mounting accessories shown in the product photos
Inspect all components before removing the factory intake. Keep the supplied components together until the intake pipe, filter, mounting points, and hose connections have been positioned correctly.
Installation and Driving Notes
- A tune is not normally required for a basic bolt-on intake on an otherwise stock RSX Base when factory sensors and hoses remain correctly connected and the system has no air leaks.
- A tune can be useful when the vehicle has several supporting modifications, but it is not a substitute for correct installation.
- After installation, check that the intake pipe, filter, brackets, couplers, hoses, and electrical connections are secure and clear of belts, wiring, bodywork, radiator hoses, and other moving parts.
- Recheck hardware after several heat cycles and listen for intake leaks or abnormal idle changes.
Wet-Weather and Filter Care
Water-ingestion caution: Avoid deep standing water and flooded roads. A low-mounted filter can draw in water if submerged. Keep splash shields and fender liners in place, inspect the filter after heavy exposure to water, and do not spray high-pressure water directly into the intake area.
Service the washable filter more often in dusty conditions. Allow the filter to dry completely after cleaning, and use the appropriate filter-care method for the filter media.

2002–2006 Acura RSX Base Cold Air Intake FAQs
Q1: Does this cold air intake fit my 2002–2006 Acura RSX Base?
A1: This kit is listed for 2002, 2003, 2004, 2005, and 2006 Acura RSX Base models. Compare the factory intake layout and mounting locations before ordering, especially on vehicles that have already been modified.
Q2: Will this intake fit an Acura RSX Type-S?
A2: No. This intake is listed for the RSX Base only. The RSX Type-S uses a different engine and intake configuration, so it should not be treated as an interchangeable fitment.
Q3: Does this RSX Base intake fit automatic and manual transmission vehicles?
A3: Check transmission-area clearance and intake routing before installation. This is especially important if the vehicle has non-original mounts, wiring, or other aftermarket components near the intake path.
Q4: What comes with the intake kit?
A4: The kit includes one performance cold air intake kit and the mounting accessories shown in the product photos. Inspect the parts before installation and keep all hardware with the kit until installation is complete.
Q5: Does an RSX Base need a tune after installing this intake?
A5: A tune is not normally required for a basic bolt-on installation on an otherwise stock RSX Base when the factory sensors and hoses are connected correctly and the intake has no leaks. A tune may be useful with additional engine modifications.
Q6: Will this intake improve throttle response?
A6: The aluminum intake pipe and cone filter are designed to reduce intake restriction and can make throttle response feel sharper in the low- and mid-RPM range. Results depend on engine condition, installation quality, and the rest of the vehicle setup.
Q7: Will an RSX cold air intake make the car louder?
A7: Expect a deeper induction sound when the throttle opens, with the sound becoming more noticeable during hard acceleration and at higher engine speed. This changes intake sound rather than exhaust tone.
Q8: Can this intake cause a check engine light or rough idle?
A8: A correctly installed intake should operate normally. A loose coupler, disconnected sensor, open breather or vacuum hose, or other source of unmetered air can cause drivability problems. Recheck clamps, hoses, fittings, and electrical connections if the idle changes or a warning light appears.
Q9: Can I drive with this intake in the rain?
A9: Normal wet-weather driving is manageable when the filter is secure and splash shields and fender liners remain in place. Avoid water deep enough to reach the filter.
Q10: Is hydrolock a risk with a cold air intake?
A10: Hydrolock is possible when an intake filter becomes submerged and the engine draws in a large quantity of water. Avoid flooded roads and deep puddles.
Q11: Is the included air filter washable and reusable?
A11: Yes. The cone filter is washable and reusable. Clean it more frequently in dusty conditions and let it dry fully before reinstalling it.
Q12: What should I check after installation?
A12: Check that the intake pipe, filter, heat-shield-style components, couplers, brackets, hoses, and electrical connections are secure. Make sure the system is clear of moving parts, start the engine, inspect the idle, and retighten the hardware after several heat cycles.
